Jerry Seinfeld

Jerry Seinfeld started using Twitter (@JerrySeinfeld)this year (“Greetings Tweetarians! I have just landed on your Planet”) and not surprisingly, his Tweets are pretty funny.

“Comedy is just complaining in an entertaining way. Enterplaining.” Or, “I’m working in Indianapolis Saturday night. I’m a huge Indy 500 fan. All racing is a sperm flashback to your first race, the Fallopian 500.”

He’s even funnier in person, but you can find that out for yourself this month when he returns to the Colosseum at Caesars Palace for a two-night engagement.

Since “Seinfeld” ended in 1998, the star has kept busy with projects in TV (“The Marriage Ref” on NBC) and film (“Bee Movie”) and a new website (www.jerryseinfeld.com), on which he posts archival footage from his many television appearances. And then there’s that world-famous collection of Porsches.

But he always makes time for his first love: stand-up.

“When I was 10 years old, I started watching stand-up comedians on TV,” he wrote on his website. “I fell in love with them and I’m just as fascinated with stand-up comedy today.”

Seinfeld recently Tweeted that playing Las Vegas is “one of my favorite gigs.” He’s close friends, he noted, with the comedian George Wallace, who performs across the street at the Flamingo..
